Eukaryotic cell mRNA transcripts can remain in the cell for hours because they are
A)stable.
B)long.
C)isolated.
D)analogous.

Question

Quizplus · Accepted Answer

Eukaryotic cell mRNA transcripts are stable because they undergo post-transcriptional modifications that protect them from degradation. These modifications include the addition of a 5' cap and a poly(A) tail, which help stabilize the transcript and prevent degradation by exonucleases. This stability allows the mRNA to remain in the cell for hours and be used for protein synthesis.
